Color yellowish, darker on the dorsum, and on the forelegs. 
Wings hyaline with brownish veins, the color being deepest 
along the radial and cubital stems. Middle and hind legs yellow, 
forelegs brownish, all legs darker on tips of tarsi. The head is 
yellow but the three terminal segments of the palpi are brown, and © 
the flagellum of the antenna is brownish; it consists of 12 oval 
segments, the last one seated styluslike on the apex of the one be- 
fore it and not fully differentiated therefrom, the flagellum hardly 
longer than the total length of the head including its short proboscis. 
The lower valves of the ovipositor are broad and obtuse at the apex } 
the upper valves are short, triangular at base, but prolonged and up- 
curved at apex; and the tips of the two pairs are nearly on a level. 
A single female specimen was obtained at Walnut, Lake Michi- 
ean on the 7th of August 1906 in a trap lantern. It will probably 
eventually constitute a new genus, but it is evidently derived from 
the more typical Dicranomyia, by a process of reduction, and it rep- 
resénts the. maximum of reduction of the median vein along this 
developmental line. | 
I take pleasure in dedicating this species to my former pupil, 
Mr C. O. Wharton, to whom I am indebted for the prepara- 
tion of the pencil drawings for most of the original figures 
of this paper, and for some other assistance toward its prepa- 
ration. : 
I wish to call attention in passing, to a number of forms 
in this family that are misplaced. Meunier’s fossil crane fly 
from amber Palaeoerioptera [ Ent. Soc. France. Bul. 68:350, fig. | 
is not a Tipulid at all but belongs to the Psychodidae.

Tipula at all. In its long m-cu cross vein, situate at the very inner 
end of the cell, 1st M., it is much more like Mice ishocete | see pl. 16, 
fig. 4] but it probably represents a new genus. 
If the two figures I have copied on plate 18, figures 5 and 6 
are at all accurate, Libnotes must be polymorphic. Whe last 
figure is probably incorrect in its representation of the wing veins 
near the costal border of the wing.
